Packed Data Policy Statement Dick Simpson MC Face-to-Face Discussion 19 April 2017
From Announcement From Announcement 13 March MC 13 March MC Telecon Telecon The Management Council did reach a decision on Packed Data. They considered three choices: 1. No packed data as a primary product in the archive without exception 2. No packed data as a primary product with the exception of DSN data and raw Radio Science data. 3. No packed data as a primary product with the exception of DSN data, raw Radio Science data, and Telemetry. The second of the three choices was selected. Option 2 will become PDS policy. We will post it to pds.nasa.gov/policy. We can spend a few minutes on next steps on the Monday telecon.
2. No packed data as a primary product with the 2. No packed data as a primary product with the exception of DSN data and raw Radio Science data exception of DSN data and raw Radio Science data OK with Simpson and Radio Science community What to do about everyone else (e.g., Document Author Team) Primary Product =? Product_Observational Effective when? IM v1.9.0.0? Immediately? Yes Deprecate? Could data providers use old IMs (as NAIF will use IM v1.5.0.0)? Retroactively? Would prohibit future use of previously allowed capability (no precedent) Allowed elsewhere? With unpacked version? Yes As Product_Native? There are issues Support? Dan: Queued with TWG Work saved? Reviews facilitated? Who oversees DSN and Radio Science screening? DSN data could include telemetry (Option 3)
Possible Policy Statement Wording: Possible Policy Statement Wording: Effective immediately, no PDS4 Product_Observational may contain a Packed_Data_Fields object. Packed_Data_Fields is allowed in other Product subclasses, if an unpacked version of the same data is also provided. DSN data and raw radio science data are exempt from this restriction. Follow Follow- -up Actions: up Actions: Suspend all current non-compliant deliveries (if any) DNs locate and convert ingested non-compliant archives (if any) Develop tool(s) to display Packed_Data_Fields
